To all whom it mayV Concern.'y

Be it known that l, Josnrr-r J. Mnnrrovrorr, I. a citizen of the United States-ofAmer1ca,

useful improvements in'rail tie chairs and has particular reference to the provision of improved means for supporting and Securing railway rails upon cross ties of the usual wooden type.- Y

The primary to provide an extremely simple and eflicient construction of rail tie chair ofthe above lrind forpermitting'securing of the rail'to the tie inan expeditious manner.

Another object of the invention is to generally simplify and improve'rail securing tie chairs.

W ith the above general objects in view and others that will appear as the nature of the invent-ion is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter.

more fully described in connection with the accompanying drawings and in which like characters of reference indicate corresponding parts throughout the severa-l views.

ln the drawing,

Figure 1 is a: transverse sectional view taken through ya rail and tie and a rail chair constructed in accordance with the present invention, l

Figure 2 is a top plan view of the rail chair shown in Figure 1 with the slidable rail engaging clips removed,

Figure 3 is a vertical Sectional view taken upon lineIII-III of Figure 1,

Figure 4l is an enlargedl perspective view of one of the slidable rail engaging clips shown in Figures 1 and 3,

Figure 5 is a view similar to Figure 1 showing a slightly modified vform of the rail chair,

Figure 6 is a view similar to Figure 2 of the form of rail chair shown in Figure 5 and with the slidable rail engaging clips in place, and

Figure 7 is a fragmentary vertical sectional view taken upon line VII-VII of Figure 5. l l

Referring more in detail to the several views, the present inventionl consists of la object of the `invention is;

rail chair embodying a flat piece of'metal or plate 5 adapted to rest upon the vupper surface of a. wooden tie 6 and to have the usualrail 7 rest thereon, the plate' Vbeing. provided along one side with a rigid or integral lip 8 formed to overhang and snugly engage. the adjacent longitudinal f edge portion of kthe adjacent base flange of the rail 7. Near'the opposite side of the plate 5 are provided apair of transversely elongated lslots 9 in which separate rail engaging clips l0 are slidably mounted, said lclips including enlarged bases 11 engaging the enlarged portions of the slots 9 which are provided by undercutting said slots as .indicated by dotted ylines in Figure 2 whereb Y the clips 10 are held against uprward displacement. The clips 10 are of such form -aste engage over the other base flange of the rail 7 and the inner ends of the slots are enlarged as yat 12 so as to permit thel passage of the bases 11 ofsaid lips after which the latter may be turnedonefourth revolution so as to be effectively held in place. As shown in Figure l, the plate 5 is disposed upon the tie 6 by slidingthe plate 5 transversely under the rail 7 until the rigid lip 8 engages the adjacent flange of said rail and the movablejclips 10 are then forced inwardly into engagement with the other flange of the rail tie by driving spikes 13 through the slots 9 between the outer ends of Said slots and the movable clips 10, thereby securing the plate. 5 to the tie and holding the clips 10 in engagevment with the rail so as to eectively hold In the modified form` of the invention` Shown in Fi ures 5, 6, and 7 the chair plate 5 is provi ed with the yrigid or integral overhanging lip 8 at one side and is also' provided with the spike holes 14 outwardly of said lip 8. At the opposite side of the plate 5 slots 9 are provided which are somewhat Similar to the slots 9 of Figure 1 but which are not quite as long nor are they enlarged. By the use of this form of By pro-Y ratentedreb; 7, 1922.-v

slot, it is necessary that the slidable clips be made in separable sections and this is clearly shown wherein the clips have separate bases 11 detachably secured to the upper portion by means of a screw 15 which screw Y slots.

The manner of employing Vthe chair shown in Figures 5 to 7 inclusive, is substantiall i the same as that set forth with respect to t e other form of the invention shown in Figures l to 4 inclusive except that the slidable clips of the first named form are assembled with the plate by removing the screws 15 and dropping the upper portions of the slidable clips downwardly through the slots 9s after which the bases are disposed into the undercut portions of said slots from beneath and then connected by said screws.

From the foregoing description, it is believed that the construction and operation passes through ,a central openingprovided 1n the base l1 and is threaded into of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the in-r vention asfclaimed. Y

What isrclaimed as new is:

A rail tie chair com risinga metallic plate` adapted' to be dispose flatly upon the upper surface of a rail tie and to have a railrest thereon, said plate having alip along one side adapted to engage over one of the base flanges of said rail and having transversely:

elongated slots adjacentthe other side wit-h clips slidably vheld in said slots, saidslots e being of such length as to permitspikes to be driven therethrough between the outer ends of the slots ,and the said clips for holding thelatter in engagement with the otherbase flange of said rail, the said slots being undercut, and the said slidable clips embody-v ing` separable head and base members, the base members being beveled on their upper surfaces so asto fitY snuglyV in the undercut portions of the said slots of the metallic plate, the head membersV adapted to rest upon the metallic plate, and screw bolt connections for the headV and'base members.VV

In testimony whereof I aflix my signature.

JOSEPH J. MARROVICH.
